Apparently there's also a textures pack because the original game apparently didn't look so good.

Is this texture pack + original game + new content all included in the digital version as well? I would assume yes but I guess I'll need to wait and see.

I've heard a rumor that the texture pack is only for the 360 version because that was the version which didn't look so good (for the original game)---http://www.gamefaqs.com/boards/615804-the-elder-scrolls-v-skyrim/64275451 - Skyrim Level 81 Guide

I believe it when I see it. Judging by the screen-shots, the graphics have not changed at all.---"When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up. -C.S. Lewis
